What type water supply and drain (DWV) pipes were commonly used for 1980s residential plumbing?
Friday, July 6, 2018
The big news of the 1980s was two new plastic water supply pipes, CPVC and PB, but copper continued to be the preferred water pipe.
Copper was most common pipe.
CPVC (cream-color plastic) was introduced in 1985.
PB (gray plastic, shown above) pipe use grew rapidly during the 1980s, due to its low cost and simple installation, especially in mobile homes.
PVC (white plastic) used for water service piping to house (not inside), and other exterior locations.
ABS (black plastic) was extensively used, but not as popular as PVC.
PVC (white plastic) was most the common DWV pipe.
See our blog post for What do the ABS, PVC, CPVC, PB, and PEX plumbing pipe names mean? for the chemical composition behind all those acronyms.
